The bones included those of an emu, one of the specimens discussed in this report. That discovery prompted a search of the QVMAG collection for other emus, of which we found several, including some of questionable provenance. At that stage the Plomley Foundation stepped in with funding to date a selection of specimens, underpinning the findings presented here. I thank the Plomely Foundation for its generosity. I also thank Senior Curator Natural Sciences, David Maynard, Collection Officer Natural Sciences, Tammy Gordon, and Library Coordinator, Andrew Parsons, for their advice and support throughout the project. I thank also the many other people at QVMAG and other institutions who assisted.

This material is older than 10 000 years provided in the table below. BP and some of it may exceed the limits of radiocarbon dating (~50 000 years BP). Three samples of bone were dated at 37 909- 33 764 calBC, 40 131-36 665 calBC and 40 799-37 138 calBC. These are the oldest dates yet obtained for emu in Tasmania. They sample the emu population at a time of colder climatic conditions and lower sea levels, when Bass Strait did not preclude mixing of emus in Tasmania and Victoria. The Pleistocene age material was collected in the Smithton area of north west Tasmania, from swamps and Scotchtown Cave. In addition to bone, the Pleistocene age material includes three small fragments of emu eggshell. These were dated 15 839- 15 421 calBC, providing hitherto disregarded evidence for the presence of emu on Flinders Island. Some eight registered and unregistered lots comprising over 200 bones and bone fragments are confirmed as dating to the iv Summary details for the respective lots are provided in the table below.
